12-acre lake in Oconto County, Wisconsin. The lake tops out around 19 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Bullfrog Lake draws 12 acres inside 0.6 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 61% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. You'll find it in Oconto County. The nearest mapped water is Wheeler Lake, 1 mi to the northwest.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. The chart's best answer is Deep basin — deep basin, 16 ft, prime for fall. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 19 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 16 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 6 to 19 ft | dawn | Break off the point (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 6 to 19 ft. Top water on the chart: Deep basin, a deep basin in the 16 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 16 ft that scores prime in winter. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (16 ft) | Tungsten ice jig + plastic, Tiny spoon |

These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Deep basin is the top-rated area: a deep basin in about 16 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
